Mixing stoker recipes together

[RockyMtn96XJ]

I'm going 4.6 with the modified poor man recipe (.020" over & stock cam). BUT, I need a new cam and lifters so I was gonna do a CompCam 68-232-4. I just wanna make sure everything is ok with this mix of recipes by adding the cam in there. Anyone have any knowledge on this? I have no idea why it WOULDN'T work, but better safe than sorry.

Thanks!
Chris

It'll be absolutely fine. With that cam you could even go slightly higher (9.5:1) with the static compression ratio.
Russ stocks a lower lift version of that cam if you want to retain the stock valve springs.

Thanks for the info 'Maniac. I'll go with the new springs for the added lift.

I want to make sure I understand what I'm buying.... The 68-232-4 KIT springs seem to have a larger OD than factory springs. So that means I will have to get the machine shop to open the spring seat where it sits to accommodate the springs that come with the kit?

I also saw someone complain about the keepers and spring caps;

"valve springs/keepers/and valve spring caps are wrong dia for 4.0 jeep engines. To big will not lock on valve stem"

I am ok with the machine shop making room for the springs... but if the keepers and caps dont work, where do I go from there? Are the factory caps good for the COMP springs? What about keepers? Use the factory style also? What a pita.... hahahaha.

Update.... 15 seconds later.

I just saw this answer from customer service on Summits site;

"Thank you for your question. COMP Cams K68-232-4 camshaft kit will not fit either the 1996 or 1998 Jeep 4.0L engine due to the valve stems seals. We apologize for the error in our fitment data and will have this corrected as soon as possible. The other components included in the kit will fit the 1996 Jeep 4.0L engine.

Camshaft - COMP Cams 68-232-4
Lifters - COMP Cams 822-12
Timing set - COMP Cams 3219
Valve springs - COMP Cams 926-12
Retainers - 744-12

Soooooooo, who's correct?
Maybe the one guy complaining had something weird going on?

I went through the same thing, you need the mopar springs and retainers PN5249464

My parts are at the machine shop now. They said they are very familiar with this type of project and assured me they know how to handle the heads/springs fitment issues and the rest of the stroker normalities. I'd hope so with such a large jeep history here in the Denver area. with the mountains and all....
I hope to get it all back in a couple weeks. Completely balanced with my harmonic balancer and flywheel/bolts. 3 angle valve job. Etc etc etc
I learned there is a special torque plate that is used when ARP head studs are used in a build. This is due to the high torque of the studs.
Needless to say, im excited to get this stuff back and installed.

Update. Motor is together and ready to go into the jeep. Ive taken a bunch of pics. I'll make a big post about my stroker project when im done with it. Id rather take pics and post all at once with a story rather than weekly updates.

A good place to post it would be in the Projects section.

I'll start a new post over there when time comes to add a bunch of useful pictures. Engine is in now, just sitting with 4 motor mount bolts in.

Hello all,

I know I’m late to the party but wanted to put it out there that I do indeed have a custom grind cam that Comp Cams makes for me that’s a significant improvement over stock but still can be utilized with a stock Valve Spring Head.

Don’t hesitate to reach out to me for further information on specs and pricing.

Thanks,
